Here, the opening in the upper part of the peripheral wall 22 is referred to as an upper opening 23.

  The outer surface of the peripheral wall 22 is provided with a second convex portion 24 that extends in the vertical direction and fits into the first concave portion 15 described above. A flange 25 is provided at the upper end of the peripheral wall 22 so as to extend outward in the radial direction. Here, the flange 25 is provided with a through-hole 26 that is formed in such a size that the above-described upward protrusion 16 can be inserted. Further, a thin plate-like wall portion 27 extending along the outer edge of the flange 25 is provided on the upper surface of the flange 25. The lower surface of the flange 25 is provided with a claw portion (engaged portion) 28 that extends downward and has a lower end protruding radially inward.

  As shown in FIGS. 1 and 4, the lid 30 includes a top wall 31 that covers the upper opening 23, and a knob 32 that is integrally connected to the top wall 31 and extends in an arc shape. The top wall 31 and the knob 32 of the present embodiment are formed by providing a dividing portion 33 extending in a circular arc shape from the outside in the radial direction to the inside in a portion where the overall shape is a disc shape. Is. In addition, the dividing part 33 in this embodiment is configured by a slit that cuts a disk-shaped part from the front surface to the back surface in the entire length in which the extending part extends, but all the extending areas are divided from the beginning. It is not limited to what is done, and it may be divided later. As such a thing, the part by which the part cut | disconnected from the surface to a back surface is provided intermittently in the part where the parting part 33 extends is mentioned, for example. In addition, the portion where the dividing portion 33 extends may be thinned. On the lower surface of the top wall 31, a seal cylinder 34 is provided on the inner side in the radial direction from the knob 32 and is fitted and held on the inner surface of the peripheral wall 22. Further, a downward projection 35 that protrudes downward and can be inserted into the through hole 26 is provided on the lower surface of the knob 32.
